Synopsis
Following a violent storm, the crew and passengers of the S.S. Minnow wake up to find that they have washed ashore on an uncharted island. The captain, Jonas Grumby (commonly known as "Skipper") and his first mate Gilligan set sail on a raft to try and return to land, while the passengers stay on the island. However, a storm blows the crew back to the island, but Skipper and Gilligan do not know that this island is the same the island on which they first landed. The passengers, meanwhile, do not know that the "crew" have returned. When both groups become aware that the other group is on the island, each group assume that the other are headhunters. In the end, everyone gets trapped in a cave, and Gilligan emerges dressed as a native scaring passengers and the rest of the crew away.
